Kymco News / Xtown vs. Forza
« on: October 29, 2017, 04:32:11 PM »
Earlier this year, I was doing my homework on the Burgman 200 and Honda Forza, and had just decided I would get a Forza when the announcements came about the Xtown 300i and Xciting 400i. My Xciting 500 was apart in the garage, waiting for parts which were needed after I did the stator replacement.

Well, the Xtown and 400i are finally here.  The Xciting 400i was pretty high on the list, but the only one available anywhere near me was black.  I don't want people to cut me off because they didn't see me, so that one was scratched off right away.  Its a shame too, because it ticked ALL the other boxes I was looking for and would have been the clear winner.   Maybe next year they will have the bike available in colors other than Invisible, we'll see what happens.

The Xtown was available in both white and gray. White is much better for visibility.  Looking at the specs between the Forza and Xtown, there was a whole ton of overlap; it seemed that they would both meet my requirements.

In the end, I got rid of the Xciting 500i.  For the 3rd time since I've owned the bike in the last 18 months, it mysteriously died while idling at a stop light, requiring a restart.  (Engine warm, everything).  I was hoping that after the battery/stator/regulator replacement, the bike would be good.  But I now always have that reliability issue in the back of my mind, so it was time to get a different bike.

Of course I still have the Xciting 250, which seems to be bulletproof - but I know enough that I want to have two bikes so that I don't miss riding days because of repairs.
The new bike was, for sure, going to have ABS, and I also wanted to be able to do 70mph without red lining the engine.  I don't do a huge amount of highway, but when I do, I don't want to be stressing the engine.

Two things caused me to choose the Forza over the Xtown.
1. The Forza runs @ around 7200rpm, with a redline of 9000, @ 70mph (NOT GPS VERIFIED YET).  The Xtown (per the dealer) redlines (which I imagine is @ 8000rpm) at 65mph.
Its important to note that this probably means that the bikes are tuned differently.  Both have around the same displacement, and compression ratio.  It is quite likely that the Xtown will be faster accelerating up until around 70mph, and will lose less speed on uphills (see below about the windshield).  But I want reliability on my bike, and running the Xtown at a likely 8500rpm (based on my experience with the XC250, which I'm assuming is the exact same engine as the Xtown but with an overbored cylinder head) is going to detract from the motor's reliability.
2.  The Forza has an 8000 mile oil service interval.  The Xtown 300i has an 1800 mile oil service interval.  I put ~ 10,000 miles per year on the bikes.  When the XC250 was the only bike I had *(which has a 1200mile service interval), it seemed like I was changing the oil all the time.

Well, I drove the Forza home from the dealer yesterday (130 mile trip).  I noticed that above 65mph, the Forza drivetrain seems to be a little bit "buzzy" than compared to lower speeds.
Acceleration or top speed wasn't tested, since the motor is being broken in. 
When I got home, I noticed that the seat isn't staying up, even though it seems to have some sort of mechanism at the front hinge which suggests it should.
Also, this is a big annoyance for me, my helmet (a Bell Revolver EVO) does NOT fit under the seat in either location (even after consulting the manual).  That in itself isn't much of a surprise (and not really the knock against the bike), as the only bike I've found which can do this is the Burgman 200.  However, the Forza's helmet hook system is CRAZY stupid.  You are required to find the loop of steel wire under your seat, thread it through the helmet's D-hook and back over itself, then hang the other end of the wire around a post under the seat.  Seriously, was a helmet hook too much for Honda to muster?  Looks like a 50L top box is going to be a mandatory accessory.
Finally the windshield on the Forza is NOT.   It is decorative only, and I think that I'll be going deaf from the wind noise @ 70mph.  The Xtown has the same tall windshield as on my '06 XC250, which does a decent job of protecting everything but the top of my helmet.  The windshield is likely to be the only thing differentiating the top speed of the Forza from the Xtown.  All other things being equal, I'd rather have a 75mph top speed with wind protection, than an 85mph buffeting machine.  This is one place where the Xtown definitely wins out on.
Addendum:  The rear suspension of the forza is VERY harsh, much more than the Xciting suspension dialed in to the highest setting.

General Discussion / Xciting 400I / Xtown 300i questions
« on: August 15, 2017, 12:35:19 AM »
I currently have an XC250 and an XC500Ri ABS
I *was* looking to replace the XC250 for something with good mileage and ABS brakes, and keeping the XC500 for long trips.
I had narrowed the choices down to the Burgman 200 and Forza, and finally decided that the Forza was the one (no loss in short run interstate ability, plus that 8000 mile oil service interval would mean only two oil changes per year instead of 6-7 on the XC250), but I just noticed the announcement of the XC400I/Xt300i.
The current reviews don't have a lot of great information, such as

Fuel tank capacity/mileage?
Oil service interval?
GPS top speed?
Most importantly, what frame is each bike a descendant of?  The Downtown would have been a good bike except for the fact that leg room was too tight, which is why I went with the Xciting frames.

Xciting 500 / 2009 Xciting 500 RI abs ECU codes
« on: July 22, 2017, 02:26:35 PM »
I have a 2009 Xciting RI ABS.  It was not charging the battery, so I ordered the stator and regulator assembly.
Pulled the bike apart and did the stator and regulator replacement.   Bike appeared dead when I attempted to start, had to replace the 30A fuse beside the starter relay.  (Something *must* have happened while doing the repair, but I don't for the life of me know what).
Then the bike was throwing two ECU codes (O2 sensor heater out of spec, Ignition coil out of spec.)
Thought it was kind of weird to have two failures, but when I checked them against the spec in the repair manual, sure enough they were outside the listed acceptable range.
Ordered a new O2 sensor and Ignition coil.  Replaced them, bike is still throwing these two codes, can't reset the codes with the procedure in the manual.
Looked at the schematic diagram and saw that the ECU pin #1 ground was common to both sensors.  Measured from pin 1 to the ground connector on the ignition coil, came up with <1 ohm. (Using a Fluke 87 meter).   Checked again from pin 18 to the ignition coil firing connected, again < 1 ohm.
At this point, the new sensors seem to check out fine, which is why I suspected the wiring harness.   Is the procedure for resetting ECU codes in the Cyclepedia service manual incorrect?  Is there something else I should be checking?  Or am I looking at a new ECU?
The bike DOES start, however the check engine light turns on.
Thanks,
Glenn
